Description
ABB RDCU-02C 64607901 Kontrolle Platte ACS800 series inverter main control board (CPU board)
[Product Positioning]
RDCU-02C 64607901 is the main control board (ISU control unit) designed by ABB specifically for the ACS800 series frequency converter, and belongs to the central core module of the frequency converter system. It integrates CPU processor, communication interface, I/O scheduling, and protection logic into one, targeting industrial drive scenarios that require millisecond level closed-loop control. It is a “brain” level presence in ACS800 frequency converters.

[Core Function]
This module simultaneously undertakes tasks such as speed control, torque control, PID regulation, motor protection, and process monitoring. The built-in CPU and FPGA hardware accelerator work together. The CPU is responsible for floating-point operations and system management, while the FPGA is responsible for protocol processing and fast I/O scheduling. The two do not compete for resources. Control tasks are graded according to speed: extremely fast tasks are as low as 25ns, fast tasks are as low as 100 μ s, and slow tasks are as low as 1ms. The full link time for reading and writing one I/O can be controlled within 100 μ s, far faster than the 50ms scanning cycle of traditional PLCs. Supports multiple driving modes such as V/F control, vector control, direct torque control (DTC), etc., and can be adapted to motors in the power range of 1.5kW to 1600kW.
Communication and Interface
Equipped with Ethernet RJ45 port, RS-485 serial port, RS-232 serial port, and CAN bus interface. Supports mainstream industrial communication protocols such as Modbus TCP/RTU, Profibus DP, DeviceNet, CANopen, Profinet, EtherNet/IP, etc. The CPU motherboard provides 1, 2, or 4 communication slot configurations, which can be expanded to up to 4 communication expansion interface modules as needed. Built in multi protocol compatibility function, supports protocol hot switching, and does not require additional protocol converters. Support expanding to 64 nodes through switches to build long-distance redundant ring networks. The front panel is equipped with a RUN/ERROR/COMM three color LED status indicator light, which can be used to determine the fault area from a distance.
[Physical Specifications]
Dimensions: 380mm × 49mm × 22mm, net weight approximately 0.5kg. Installed on a 35mm DIN rail. The front panel protection level is IP20 (with a frequency converter cabinet that meets NEMA 4X). The working temperature range is -25 ° C to+70 ° C (UL certification range -30 ° C to+65 ° C), and the storage temperature is -40 ° C to+85 ° C. It has a fanless design, no electrolytic capacitors, natural cooling, and can operate stably for a long time in vibration and strong electromagnetic interference environments. Origin Switzerland.
Power Supply and Certification
The working power supply is 24V DC (18-32V DC), with typical low power consumption. Passed certifications such as CE, cULus, UL 508, RCM, RoHS, etc. Compliant with IEC 61000 series electromagnetic compatibility standards and ISA S71.04 G1/G3 environmental grade requirements. HS code 84714100.
Programming and Configuration
Use ABB Drive Composer or System Builder software for parameter configuration and debugging, or perform local operations through panel buttons and built-in display screens. Support remote parameter configuration and online diagnosis for quick fault location. Built in web server, supports remote monitoring.
[Typical Application]
Widely used in industries such as power, petrochemicals, metallurgy, smart water management, mining, and shipbuilding. Typical scenarios include: speed regulation of large fans, constant pressure water supply of water pumps, speed synchronization of conveyor belts, start stop control of compressors, and precise driving of rolling mill main drives that require high-power motors. Usually used as the core control unit of ACS800 frequency converter, it is paired with AINT-02C I/O board, APOW-01C power board, FS300R12KE3/AGDR-61C driver module, RINT5514C main circuit board, etc., to form a complete frequency conversion drive system.
Comparison with the same series
RDCU-02C is a standard single CPU configuration, suitable for small to medium power and medium complexity applications. RDCU-12C is an enhanced dual CPU configuration suitable for high-power or high reliability redundant scenarios. The two are electrically compatible and can be optionally selected on the same ACS800 platform as needed.
